The deprecated feature to upload JAR files with classes, and to use classes from previously uploaded JAR files in workflow process definitions has been disabled by default, and may be removed in a future release. Required classes should be added to the Workflow Server classpath instead.

If still needed, the possibility to upload and use JAR files with workflow process definitions can be enabled again by setting deprecated Workflow Server configuration property workflow.server.use-uploaded-jar to true. However, it is recommended to keep it disabled, also to avoid potential problems of storing executable code in the database.
